This invention relates to mountin s for electrical conductors the like, whereln the same are suspended from a system of poles or other means which suitably resist the elements and carry the wires at a desired breaking of the wire and kbending thereof at th accompanying drawings,

Figure 1 is a front elevation, section, of a form of my device.

igure 2 is a side elevation, partly in section of the device shown in Figure 1 and sectioned on the line 2-2.

Figure 3 is a front elevation of a modified form of the invention.

80 partly in Figure 4 is a section on the line 44 of Figure 3 and looking in the direction of the th arrows.

In the drawings a represents the cross arm of a pole, tower or other structure from which a transmission line is suspended. To

the arm a, a bracket 6 is secured, as by bolts f the bracket is which serves as er non-metallic Cover e is bolted to c. The lower extremity of 5 constructed as a housing Z2 a seat for a rubber, or 0th cushioning element d. the housing 6' by meansof bolts 7 passing through ears 6' of the cover 6. The rubber I element d is formed larger than the housing e wire due to variations (1 resent invention is to or conductors, particuts larly of the type above mentioned, which g at th 1926.
